ASP Migration Service

Legacy ASP systems face numerous challenges, including an outdated technology stack, a shrinking talent pool, end of support for ASP and ASP-dependent components, etc. Failures or delays in modernization can lead to system outages, compliance risks, and loss of competitive advantage.

SoftRoad has helped many customers migrate legacy ASP systems to modern technologies such as ASP.NET, Java, and also supported .NET framework upgrades. Using our proprietary AI-assisted conversion technology, supported by structured analysis, validation, and engineering review, we migrate legacy ASP code and data to pure ASP.NET or Java systems that fully comply with industry standards. The resulting systems are rigorously tested for superior quality, highly maintainable, and generative AI–ready for future maintenance and enhancement.

Success Stories

With our unparalleled AI-assisted modernization technology, supported by structured analysis, validation, and engineering review, we help our clients with their ASP modernization initiatives, delivering a standard compliant open system with high quality and low costs, which sets us apart from the competition.

A number of our clients presented their migration projects as case studies jointly with SoftRoad at major IT events in Japan. Cover pages shown below are from slides for those speaking sessions.

Case studies reference specific modernization projects delivered across different timeframes and regions. Brand names are used for illustrative purposes only and do not imply endorsement or ongoing commercial relationships.

Inevitable Classic ASP System Migration

Continuing to use the classic ASP system will lead to various problems.

Common Problems in ASP Migration

Lack of expertise · Problematic migrations are common

Manual or semi-automatic migration by maintenance team.

Manual trial-and-error approaches for ASP migration lead to high costs and low quality.

Lack of understanding of how migration bugs occur during ASP migration and absence of proper testing tools lead to high costs and poor quality.

Migration bugs arise from subtle differences between third-party products, languages, etc.
Similar to new developments, post-migration testing of business functions requires significant time, and testing omissions are common. It often ends up with leaving final verification to customers.

By covering all technical points, our unique testing technology ensures exceptional quality, singificantly reduced costs and man-hours.

Remarkably High Quality and Low Cost Compared to Rewriting

※¹ This is mainly a fine-tuning of the screen and report UI, and does not affect business logic.
※² JUAS (Japan Users Association of Information Systems) states that the industry-standard post-release bug rate is 0.084 to 0.1 per thousand lines of code (KL).
※³ Since business logic processing can be converted with automation, the number of defects in the business logic portion is extremely low. Minor issues such as display position issues may occur, but this will not affect the use of the system.
